* net: dns: fix for DNS queries sent to the wrong MAC addressGerhard Sittig2014-09-16-0/+3
| | | | | | | | | | | | | | | | | | | | | When a DNS query is sent out, the ethernet packet can get directed to the MAC address of a server that was communicated to before. This is wrong when the previously stored MAC address corresponds to a different server's IP address, i.e. when the IP address of the previous and the current communication are different. The error can get reproduced by running a sequence of e.g. a TFTP download and a DNS query, where the TFTP and DNS servers reside on individual machines. The fix is to clear the server's MAC address that might be left from a previous operation, and to fetch the peer's MAC address in a new ARP lookup, before the DNS query is sent. This is the approach taken in other network services, like 8e52533d1095 ("net: tftpsrv: Get correct client MAC address").

* net: More BOOTP retry timeout improvementsThierry Reding2014-08-21-8/+40
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It's not unusual for DHCP servers to take a couple hundred milliseconds to respond to DHCP discover messages. One possible reason for the delay can be that the server checks (typically using an ARP request) that the IP it's about to hand out isn't in use yet. To make matters worse, some servers may also queue up requests and process them sequentially, which can cause excessively long delays if clients retry too fast. Commit f59be6e850b3 ("net: BOOTP retry timeout improvements") shortened the retry timeouts significantly, but the BOOTP/DHCP implementation in U-Boot doesn't handle that well because it will ignore incoming replies to earlier requests. In one particular setup this increases the time it takes to obtain a DHCP lease from 630 ms to 8313 ms. This commit attempts to fix this in two ways. First it increases the initial retry timeout from 10 ms to 250 ms to give DHCP servers some more time to respond. At the same time a cache of outstanding DHCP request IDs is kept so that the implementation will know to continue transactions even after a retransmission of the DISCOVER message. The maximum retry timeout is also increased from 1 second to 2 seconds. An ID cache of size 4 will keep DHCP requests around for 8 seconds (once the maximum retry timeout has been reached) before dropping them. This should give servers plenty of time to respond. If it ever turns out that this isn't enough, the size of the cache can easily be increased. With this commit the DHCP lease on the above-mentioned setup still takes longer (1230 ms) than originally, but that's an acceptable compromise to improve DHCP lease acquisition time for a broader range of setups. To make it easier to benchmark DHCP in the future, this commit also adds the time it took to obtain a lease to the final "DHCP client bound to address x.x.x.x" message.

* net: BOOTP retry timeout improvementsStephen Warren2014-08-09-11/+34
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, the BOOTP code sends out its initial request as soon as the Ethernet driver indicates "link up". If this packet is lost or not replied to for some reason, the code waits for a 1s timeout before retrying. For some reason, such early packets are often lost on my system, so this causes an annoying delay. To optimize this, modify the BOOTP code to have very short timeouts for the first packet transmitted, but gradually increase the timeout each time a timeout occurs. This way, if the first packet is lost, the second packet is transmitted quite quickly and hence the overall delay is low. However, if there's still no response, we don't keep spewing out packets at an insane speed. It's arguably more correct to try and find out why the first packet is lost. However, it seems to disappear inside my Ethenet chip; the TX chip indicates no error during TX (not that it has much in the way of reporting...), yet wireshark on the RX side doesn't see any packet. FWIW, I'm using an ASIX USB Ethernet adapter. Perhaps "link up" is reported too early or based on the wrong condition in HW, and we should add some fixed extra delay into the driver. However, this would slow down every link up event even if it ends up not being needed in some cases. Having BOOTP retry quickly applies the fix/WAR to every possible Ethernet device, and is quite simple to implement, so seems a better solution.

But smaller amount of modification is preferable. Additionally, we need to fix compiler flags which are locally added or removed. In Kbuild, it is not allowed to change CFLAGS locally.
